[lldb] Inform every language runtime of the modified modules
When a process is notified that modules got loaded, currently only
existing language runtimes are given a chance to deal with that. This
means that if the runtime for a given language wasn't needed before it
won't be informed of the module chance.
This is wrong because the module change might be what triggers the need
for a certain runtime. Instead, we should give the language runtime for
every supported language a chance to deal with the modified modules.
